Genie's Vessel as a Prison?

Please disregard. I can't read.

The imprisoned creature could destroy the vessel from the inside, if they're not suitably restrained and restricted from acting. Even unarmed strikes will wear it down in a matter of minutes (assuming the creature's strength isn't lower than 10).

Sorry if this has been posted before, but can you use the genie's vessel from the Genie Warlock as a prison?

Sanctuary Vessel
At 10th level, When you enter your Genie's Vessel via the Bottled Respite feature, you can now choose up to five willing creatures that you can see within 30 feet of you, and the chosen creatures are drawn into the vessel with you.

As a bonus action, you can eject any number of creatures from the vessel, and everyone is ejected if you leave or die or if the vessel is destroyed.

In addition, anyone (including you) who remains within the vessel for at least 10 minutes gains the benefit of finishing a short rest, and anyone can add your proficiency bonus to the number of hit points they regain if they spend any Hit Dice as part of a short rest there.

So, they key is that they must be willing creatures, but what if you use suggestion and tell them to go into the vessel with you? From their perspective, it doesn't seem harmful. It's about the same as "walk into this prison cell".

The next interesting thing is that nowhere in here does it state how the willing creatures escape other than by the warlock's bonus action to eject them.

Now obviously doing this would render this feature worthless to the party, so you couldn't use your bottled respite safely. That being said, the creature could be starved or moved to an antimagic field, or moved into a force cage before breaking the vessel.

Thoughts?

It's only a prison if you are trapped in their with them, because there is another way to escape, "and everyone is ejected if you leave".

In defence of the idea: As a utility ability at level 10 in a presumed uncommon-ish sub-class, I'd assume this is not exactly common knowledge, so can *threaten* to leave them in here for 1000 years or whatever. And if the DM bites you can homebrew something.

Side note: I'd not bite on such a homebrew. This stinks of some kinda abusable and is likely why its designed the way it is.
